  1. Tried this variant after long. Had great fun. I always have problems with this variant thanks to my poor eyesight. The 6,8 9 all look the sane :). Thanx for clarifying.

  2. Solved without copying the box 5 clues and in the end found them as I was running into multiple solutions. Time =7:15 but it may not be a fair representation.

    I also had to use a microscope to differentiate 6/8/9.

    Overall a nice grid. Especially liked the clues with 1 and 2 givens.

  4. 5:42.I broke it the first time because of misreading the clues.Use a different software for creating sudoku images.The image quality is terrible in this. 6s look like 8s.
